``Prior Art'' Conventionally, this type of floor joint device for buildings consists of a pair of base rails each fixed to the opposing upper edges of a building frame divided into left and right parts with a plurality of bolts, and this pair of base rails. It consisted of a joint plate that covered the gap between the frameworks supported by the rails, and a pair of joint plate covers that were respectively attached with screws or the like to the top of the pair of base rails that covered both sides of the joint plate. .

However, with this structure, if the floor surface gets wet with rainwater, water will flow from the floor surface through the joint plate and enter the base rail, and the water that has entered the base rail will leak into the base rail. The problem was that the bolts penetrated into the building structure through the bolt holes that fixed the rails, causing stains and corrosion on the ceiling of the downstairs floor.

For this reason, recently a gasket has been installed at the bottom of the base rail to prevent water from entering the building structure through the bolt holes.

However, since the base rail is heavy, there is a drawback that it takes time to lay the packing, and if the packing is installed with the packing shifted or wrinkled, water can leak out from the bolt holes as mentioned above. The problem was that they could get in and stain and corrode the downstairs ceiling.

"Effects of the Present Invention" As is clear from the above explanation, the present invention has the following effects.

(1) When the floor surface becomes wet due to rainwater, etc., it is equipped with a gutter mechanism that can drain water from the floor surface through the joint plates and into the base rail fixed to the upper edge of the structure with bolts to the outside. Therefore, even if the floor surface becomes wet with rainwater or the like and water enters the base rail from the floor surface through the joint plate, the intruding water can be drained to the outside by the gutter mechanism. Therefore, it is possible to reliably prevent water from entering the frame through the bolt holes of the base rail as in the conventional case.

(2) With (1) above, it is possible to reliably prevent water from entering the building structure through the bolt holes of the base rail, thereby preventing stains and corrosion on the ceiling below the floor. can.

(3) According to (1) above, it is possible to reliably prevent water from entering the building frame through the bolt holes of the base rail, so there is no need to lay waterproof packing under the base rail as in the past. Therefore, the installation work of the base rail can be carried out easily and in a short time.

(4) If anti-slip unevenness is formed on the lower surface of the base rail, when the base rail is fixed by tightening bolts, it can be fixed without causing any displacement or the like. Therefore, the fixing work can be done easily.

(5) If the left and right building blocks are shaken back and forth due to an earthquake, etc., the seat holders can move back and forth relative to the guide rails to absorb the movement. Furthermore, when the left and right frames swing in the vertical direction, the seat holder rotates relative to the guide rail to absorb the movement.

Therefore, damage to the blocking sheet can be efficiently prevented.

(6) Since the seat holder moves forward and backward as well as rotates up and down, even if the left and right structures shake back and forth, up and down, and left and right due to an earthquake, the movement of the seat holder relative to the guide rail absorbs it. Therefore, damage to the shielding sheet can be more reliably prevented compared to the conventional method in which damage is absorbed by deformation of the shielding sheet.
